A Single-Zone System allows only one source to be heard throughout the house at a given time. However, if the system is configured to be a Multi zone system it would offer the household more flexibility. In a two-zone system, the children could watch TV in surround sound while Mom and Dad read the paper and listen to music in the living room.

Advantages of using the SI-1230 in a Single Zone System

In order to connect multiple pairs of speakers to a single stereo amplifier, they must connect in parallel to offer the best sound quality and to allow the convenience of an individual room volume control. Because parallel connections of multiple speak- er pairs lower the overall impedance presented to an amplifier, damage may occur. An impedance matching device will allow amplifiers to safely play multiple pairs of speakers. However, the amount of power actually delivered to the speakers when all of the speakers are playing simultaneously is very low. Typically a 100 watt stereo amplifier with an impedance matching device will deliver about 5 watts to each speaker in a system comprised of six pairs of eight ohm speakers. By connecting an SI-1230 to the preamplifier outputs of your stereo receiver (or preamp) you dedicate a robust 30 watts to each speaker in your multi-room system. Since each channel has its own level control, you can compensate for architectural differences that cre- ate sonic imbalances. In addition, you can fine tune the system so that when all of the room volume controls are set to the loudest level, the large rooms and the small rooms play at the same volume.
